Golf club head

ABSTRACT

An improved golf club head includes a body, a balance weight and an upper lid. The body has a hitting surface and a recess formed on an upper side of the rear end thereof. The balance weight is located in the recess. The upper lid is made from a composite material or fibers and has a curvature matching the upper side of the golf club head to anchor the balance weight in an integrated manner. Thus the weight of the upper side of golf club head is reduced. The upper lid makes the club head more appealing and can generate a crispy sound when hitting golf ball. A higher trajectory track may be generated when the golf ball is hit. And more versatile appearances may be formed.

FIELD OF THE INVENTION

The present invention relates to an improved golf club head andparticularly to a golf club head that has a reduced weight on the upperside, forms a higher trajectory track for the hitting golf ball, iseasier to strike, looks more appealing and provides more versatileappearances, and generates a crispy sound when the golf ball is hit.

BACKGROUND OF THE INVENTION

With increasingly rising of people's living standard, golf populationalso grows continuously. Playing golf has to use various types andnumbers of golf club heads. The golf ball trajectory track is a bigconcern for golfers. Many golf club heads are made in an integratedmanner. Such types of heads often are heavier and move the gravitycenter forwards and make swinging of golf club more difficult. Thesedays some golf club heads are made with a hitting panel of a smallerweight. But these types of heads have difficulty to lower the gravitycenter. As a result, striking stability is difficult to improve. To meetthe requirement of making the gravity center of the golf club head lowerand backward, a balance weight has to be added on the bottom plate. Suchan approach makes the head heavier and swinging of the golf club moredifficult. In the golf game, a good golf club and club head is importantand they could determine win or loss. It has to match the swingingposture and habit of the user and to be adjusted to get the optimumgravity center location so that swinging of the golf club is smooth andhitting the sweet spot is easier. Due to every person has a differentswinging posture and habit, at present the gravity center of the clubhead is mostly located in the center. Hence a small deviation ofswinging could result in loss of the standard hitting point and miss thesweet spot. To match different swinging postures and habits, reducingthe weight of the club head is necessary. It is usually accomplished byadding a balance weight on the hitting side to adjust the gravitycenter. Such a structure is difficult to fabricate. Once the location ofthe gravity center is set, it cannot be changed. To change the locationof the gravity center, users have to buy a new club head. It is costlyand not very practical. In short, the present club heads generally aredifficult to reduce the weight and results difficulty in swinging of thegolf club. The appearance of the club head is plain and not versatile.It also cannot generate a crisp sound when the golf ball is hit.

SUMMARY OF THE INVENTION

In view of the aforesaid disadvantages, the present invention aims toprovide an improved golf club head.

The primary object of the invention is to reduce the weight of upperside of the club head and generate a crisp sound when the golf ball ishit. It mainly has a balance weight disposed in a matching recess formedon an upper side of the club head. An upper lid made from a compositematerial or fibers with a curvature matching of the upper side of theclub head is bonded thereon in an integrated manner to anchor thebalance weight.

The club head according to the invention includes a body, a balanceweight and an upper lid. The body is integrally made from titanium byforging. It has a hitting surface on the front side and a recess formedon the upper side of a rear end thereof. The balance weight is locatedin the recess and covered by the upper lid.

The balance weight mates the recess and has apertures formed thereon toreduce the weight of the club head (or may be added to the weight ofother areas to adjust the gravity center location).

The upper lid is made from a composite material or fibers with acurvature matching the upper side of the club head.

The foregoing, as well as additional objects, features and advantages ofthe invention will be more readily apparent from the following detaileddescription, which proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 1, the golf club head according to the inventionincludes:

-   -   a body 1 made from titanium by forging in an integrated manner.        It has a neck 10 on a lateral side with an insert hole 100 to        couple with a shaft 4. The body 1 has a hitting face 11 on the        front side and a recess 13 formed on an upper side 12 at the        rear end. The recess 13 holds a balance weight 2 which is 2 b        and 2 c have respectively apertures 20 b of the same size or        apertures 21 c of different sizes formed thereon.

Refer to FIGS. 6 and 7 for yet another two embodiments of the presentinvention. It is constructed substantially like the embodiment shown inFIG. 1. However, the balance weights 2 d and 2 e have respectivelyelongated troughs 20 d and arched troughs 20 e formed thereon.

Refer to FIGS. 8 and 9 for still another two embodiments of the presentinvention. It is constructed substantially like the embodiment shown inFIG. 1. However, the balance weights 2 f and 2 g have respectively upperarched troughs 20 f and lower arched troughs 20 g formed thereon.

Refer to FIG. 10 for another embodiment of the present invention. It isconstructed substantially like the embodiment shown in FIG. 1. However,the balance weight 2 h has transverse troughs 20 h formed thereon.

By means of the constructions set forth above, the invention can providethe following advantages:

-   -   1. A balance weight with apertures or grooves of different        shapes may be mounted on the upper side of the club head, and        covered by an upper lid to reduce the weight of the upper side        of the club head. It can be adapted to different swinging        postures and habits of golfers. And it can generate a crisp        sound when hitting gold ball.    -   2. The invention has a wide range of applicability and can a        plate of an uniform thickness. The balance weight 2 has a shape        mating the recess 13 and has apertures 20 formed thereon. There        is an upper lid 3 covering the balance weight 2 from above. The        upper lid 3 is made from a composite material or fibers. The        upper lid 3 has an upper surface 30 which forms a curvature        matching the upper side 12 of the body 1 and has a shape mating        the recess 13. The upper lid 2 is located above the balance        weight 2 and compressed to become integrated therewith.

For assembly (referring to FIG. 2A), the balance weight 2 is placed inthe recess 13 on the upper side 12 of the body 1. Then dispose the upperlid 3 thereon to anchor the balance weight 2 on the upper side 12 of thebody 1 (as shown in FIG. 2B). Thus the weight at the upper side of thebody 1 is reduced. And the location of the gravity center may beadjusted. As the upper lid 3 is made from a composite material orfibers, it makes the club head more appealing and versatile. It also cangenerate a crispy sound when hitting golf ball.

Refer to FIG. 3 for a second embodiment of the present invention. It isconstructed substantially like the embodiment shown in FIG. 1. Thedifference is that the balance weight 2 a has a flat surface.

Refer to FIGS. 4 and 5 for another two embodiments of the presentinvention. It is constructed substantially like the embodiment shown inFIG. 1. However, the balance weights uniform fabrication of the clubhead. By forming apertures and grooves of different shapes on thebalance weight, desired results may be achieved. Manufacturing time andcost may also be reduced.
